Castles of g3 found in g4?

[ManaMinori 4,143]

 

Because gen 3 is so similar to gen 4, by way of locations, characterization, etc. I have to wonder if the castles that Spike shows in "The Runaway Rainbow" also bear resemblance to the ones of gen 4.

 

On a map, there are several castles, which are said by Spike to celebrate something different- a yellow one celebrates happiness, a purple one celebrates friendship (which could equate to Twilight's castle), sky blue for family, green castle does kindness, and there are others that celebrate music, laughter, and rainbows.

 

What castles do you guys think these relate to, in g4 Equestria?
